[CARBONDATA-3914] We are getting the below error when executing select query on a carbon table when no data is returned from hive beeline.

Description

If no data is present in the table, then we are getting the below IOException in carbon, while running select queries on that empty table. But in hive even if the table holds no data, then it is working for select queries.

Expected results: Even the table holds no records it should return 0 or no rows returned. It should not throw error/exception.

Actual result: It is throwing IO exception - Unable to read carbon schema.
